I just put a new cam in my Pentastar V6. Can somebody explain how the VVT actually works?
I can see there are some solenoids on the end that presumably shift something inside the cam phasors. The cam phasors have coil springs around them. And there there's this big "oil control bolt" that's all full of holes, so the thing is probably actuated by oil pressure counteracting the mechanical spring pressure, triggered by the solenoids. But I just can't visualize how it actually works.
